Rainbow Rage

Red, orange, yellow, green, blue, indigo, violet - the colours of the
rainbow. Easy right? Better think again, because this isn't your average
rainbow. Big Potato are excited to present their most tense,
all-or-nothing game to date: Rainbow Rage. The rules are simple: flip a
rainbow card, spot the difference and race to grab the two colours which
have swapped places. Spot a perfect rainbow card (with all the colours
in the right order) and shout "Rainbow!" to pick up a colour of your
choice. Once you've collected every colour and built your own perfect
rainbow to victory, you're declared the winner. Doesn't sound too
stressful? Well watch out, keeping hold of your colours isn't as easy as
you might think. Grab the wrong colour? Return one to the middle. Grab
both wrong colours? Return two to the middle. Over excitedly yell
"Rainbow!" at the wrong moment? Return all of your colours to the
middle. Strap yourself in and get ready to tame some rainbows!
